PROBLEM TO BE SOLVED: To provide a game machine capable of properly terminating a presentation, even if a lower-level control part failed to receive a termination command that is sent from an upper-level control part and that instructs to terminate the presentation.SOLUTION: When a start command is sent from a presentation control board 130, a vibration operation of a presentation accessory 7, for example, is started by a control of a lamp control board 150. And, the lamp control board 150, if receiving a termination command from the presentation control board 130, terminates the vibration operation of the presentation accessory 7 at a timing receiving the termination command. On the other hand, if the termination command has not been received even after a timing by which the termination command should have been received, the lamp control board 150 terminates the vibration operation of the presentation accessory 7 by an independent determination.SELECTED DRAWING: Figure 9 |
